Overfishing and disease have decimated shellfish populations in many of the world's temperate estuarine and coastal ecosystems. Smithsonian scientists, led by Whitman Miller, ecologist at the Smithsonian Environmental Research Center in Edgewater, Md., have discovered another serious threat to these valuable filter feeders—rising levels of atmospheric carbon dioxide that contribute to the acidification of open ocean, coastal and estuarine waters.

New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. [...more]
The critical role of forests as massive "sinks" for absorbing greenhouse gases is "at risk of being lost entirely" to climate change-induced environmental stresses that threaten to damage and even decimate forests worldwide, according to a new report released today. [...more]
Quietly in public, loudly in private, climate scientists everywhere are saying the same thing: it's over.
The years in which more than 2degrees of global warming could have been prevented have passed, the opportunities squandered by denial and delay. On current trajectories we'll be lucky to get away with 4degrees.

Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. A study to be published online March 13, 2009 in Geophysical Research Letters by researchers at the Carnegie Institution and the Hebrew University of Jerusalem warns that if carbon dioxide reaches double pre-industrial levels, coral reefs can be expected to not just stop growing, but also to begin dissolving all over the world.

At first blush, global warming seems to be a great hook for those of us promoting animal-friendly eating, but there are two problems: [...more]
Global climate change is directly related to agriculture through the loss of wilderness to farmland, methane released from animals, and energy-intensive fertilizers, pesticides, food processing and transportation. [...more]
To avoid creating greenhouse gases, it makes more sense using today's technology to leave land unfarmed in conservation reserves than to plow it up for corn to make biofuel, according to a comprehensive Duke University-led study. [...more]
It may seem odd timing that many of us are heading to the nation's capital early next month for a major act of civil disobedience at a coal-fired power plant, the first big protest of its kind against global warming in this country. [...more]
Without decisive action, global warming in the 21st century is likely to accelerate at a much faster pace and cause more environmental damage than predicted, according to a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change. [...more]
